Description

is designed to be foldable, kinks cannot be avoided in the long run. Since these kinks are also in Continuing the bobbin creates faulty bobbins that are difficult or impossible to move can be further processed.

Furthermore, a spool for producing endless synthetic threads from organic material is known fs German utility model 1901080), which the to replace known coils made of metal by a much lighter construction, including mechanical Strength is sought. This coil is not flangeless. The end disks of the coil and their hub are made from one piece by injection molding

s made of glass fiber reinforced thermoplastic material. This coil is rigid, serves a completely different purpose and is not suitable as a winding tube for glass threads in the course of their manufacture

In addition, it is known moldings made of plastic with glass fibers in fabric, mat or Rovineform and the like. Amplify (to improve their mechanical Fioenschaften s. UGA.-Patentschrifi XnTy> \ Q and Harro Hagen, "fiber strengthened plastics «, Springer Verlag 1961, pp. 253 to 258).

Fig. 2 on an enlarged scale schematically in perspective illustration of a section from the wall of the sleeve according to FIG. 1 with illustration further details.

The winding tube 1 may have the shape of a hollow cylindrical structure. Section A in FIG. 1 is shown on an enlarged scale in FIG. 2. FIG. 2 shows that the armature of the winding tube consists of a structure which in turn has the circumferential threads 2 and the circumferential threads 3. These threads can consist of glass fibers, for example. They can be woven with each other in the classic way, or at the points of intersection only by visual welding (or gluing) and have large or loose meshes. The spaces 4 of the meshes formed by threads 2 and 3 are filled or filled with pliable plastic material . Filled in. Order the plastic material from one of the types described above.

This results in irregularities in the 30 spinning bobbins, through which the further processing of the The invention relates to spinning bobbins which hit the winding heads, which are made very difficult or impossible to insert, thin-walled, flangeless winding tubes.

In this case, however, it is practically impossible In the mechanical extraction process, the gc-40 becomes the winding core, as is often the case for those who are further processed Material through holes in a spinning absolutely necessary from the spinning bobbin nozzle to separate thin filaments or filaments, since the spinning from the spinning bobbin on the tube pulled out, the filaments to a spun thread exerted force is too great. Searching for the In summary, and the spun thread is pulled out at the same time, the end of the thread is more difficult and leads to damage and wound up. This is done by using a large 45 gene on the sleeve, which as a result is quickly replaced rotating winding head (spindle) on which must. the one referred to as a winding sleeve (cuff) according to a proposal that was not previously published Carrier is attached.

Overall, the outer surface must be roughened for winding and unwinding the sleeves have high dimensional stability and glass fibers or threads, with the inne-form stability have, because a deformation of the 55 ren and outer paper layers one approximately in the direction Coil leads to difficulties in further processing processing.

In addition, the sleeve must be able to be folded up in a very special way. The structure of this sleeve is Have surface properties. The thread should be relatively complicated. The case is not included Winding adheres well to the surface and is resistant to moisture and sizing, and do not slip on the surface of the sleeve. However, their mechanical properties are sufficient for that The threads must not get stuck on the surface. because this leads to difficulties in down-speed and very high rotary guides would. Because the threads with a liquid speed do not come out. Since the sleeve together
